What is the reaction between acidified potassium dichromate and ethanol?
When acidified potassium dichromate is reacted with ethanol, the dichromate ion (Cr2O7^2-) is reduced to chromium(III) ion (Cr^3+). This reaction results in the formation of green chromium(III) sulfate (Cr2(SO4)3), with ethanol being oxidized to acetic acid.
What is the chemical reaction of potassium dichromate with sulfuric acid?
When potassium dichromate reacts with sulfuric acid, the following reaction takes place: K2Cr2O7 + 2H2SO4 -> Cr2(SO4)3 + K2SO4 + 2H2O + 3O2. This reaction results in the formation of chromium(III) sulfate, potassium sulfate, water, and oxygen gas as products.
Which acid must be added to potassium dichromate to acidify it?
Potassium Dichromate (VI) can be acidified with sulphuric acid AND hydrochloric acid! Note that another common oxidising agent ' Acidified Potassium Manganate (VII)' is sometimes used although this one can only be acidified with sulphuric acid not hydrochloric as the Manganate (VII) oxodises the Cl- ion instead!
What is the product of reacting potassium dichromate with hydrochloric acid?
The reaction between potassium dichromate and hydrochloric acid forms chromic chloride, chlorine gas, and water. This reaction is a redox reaction, as the potassium dichromate is reduced while the hydrochloric acid is oxidized.
What is the reaction between sulfuric acid and potassium nitrate?
When sulfuric acid reacts with potassium nitrate, it forms potassium sulfate, nitric acid, and water.

What is the formula for acidified potassium dichromate?
This is a mixture of 2K+ and Cr2O72- ions in strong sulfuric acid, made from potassium chromate.2CrO4- + 2H+ ----> Cr2O72- + H2Ochromate-yellow -> dichromate-orangeNote:Potassium ions do NOT react, they are tribune-ions
What is the product of reacting potassium dichromate with hydrochloric acid?
The reaction between potassium dichromate and hydrochloric acid forms chromic chloride, chlorine gas, and water. This reaction is a redox reaction, as the potassium dichromate is reduced while the hydrochloric acid is oxidized.
What is the reaction between sulfuric acid and potassium nitrate?
When sulfuric acid reacts with potassium nitrate, it forms potassium sulfate, nitric acid, and water.
Equation of laboratory preparation of acetic acid?
Acetic acid can be prepared in the laboratory through the oxidation of ethanol using an oxidizing agent such as potassium dichromate or potassium permanganate in the presence of a catalyst like sulfuric acid. The reaction produces acetic acid, water, and other byproducts. The balanced chemical equation for this process is: C2H5OH + 2[O] → CH3COOH + H2O
In the neutralisation of sulfuric acid by potassium hydroxide what displaces the hydrogen in the acid?
Potassium displaces the hydrogen in sulfuric acid when reacting with potassium hydroxide to form potassium sulfate and water.
How do you obtain acetic acid from ethanol?
Fermentation. This is an action by microbes where they turn ethanol to ethanoic acid. For example, vinegar is made from fermented wine. H H H- C- C- OH + O2 H H Ethanol + Oxygen v H H- C- C= O + H2O H \ OH Ethanoic acid + WaterApologies for the poor chemical diagram, repeated spaces are omitted.
What is the product of p-aminobenzoic acid and ethanol?
p-aminobenzoic acid and ethanol in the presence of sulfuric acid yields benzocaine.
What is the balanced equation between potassium dichromate and oxalic acid?
The balanced equation between potassium dichromate (K2Cr2O7) and oxalic acid (H2C2O4) is: K2Cr2O7 + 3H2C2O4 -> Cr2(C2O4)3 + 2K2C2O4 + 4H2O
How would you prepare 24-dinitrobenzoic acid from p-nitrotoluene?
The reaction is possible in the presence of sodium dichromate and sulfuric acid.
